So I am very new to saltwater, and I'm starting to think about what corals I want to put in the tank. I understand the different levels of aggression, but I'm wondering how to put everything together. I have a fluval edge with some live rock that I'm going to attach everything to, but I dont know how to plan this out. I would like mostly the bright vibrant colored corals (this tank is for my girlfriend and she likes bright colors). I just dont understand how all the different ones get along. Is their some kind of method behind setting this up, or is it really just put them in and see how they settle it out?

A few that I know she would like (and I would like to put in the tank) would be:

obviously im not looking to put all these in the tank, i dont think thats close to possible (unless Im wrong), but I think she would like a combination of these, or maybe someone else can suggest some more? I would just like to have some long flow-ie ones with some shorter ones in between (obviously the more vibrant, the better). Anyone have any suggestions here?

Just do research on everything u want. As long as there is room and they don't emproach on eachother the sky is the limit. Some can multiply like mad ( mushrooms i cant sell them fast enough) Just take into account the needs of them. I almost got a sun polyp b4 I found out u had to hand feed it every other day.
With this hobby you can never research enough
